Thanks for clarifying.. Though i am not sure what for-pay, closed source, binary blob is.... I think i understood the rest of it. If the memory card is formatted in a file system that maemo recognises, it will read it.. right? Just like a pc does? no size limitation... But then i have another doubt.. Does that mean the memory card has to be formatted for usage? I mean... if i am to use a memory card used in another phone with a different file system, it wud read without formatting right? (i am talking abt smaller size cards... below 8gb?) Pardon me if the question sounds stupid..
